Paul,
this file is proven bolt hole positions based on cmm data for bell housing.
It appears the low power rx8 engine may have a different rear plate.
With the plate being cnc machined, I would make several versions based
on the housing they are using.
Easy enough, once the programs are written.

Yes I think you are right. I suspect the only difference is down on the left side
where the auto tx starter is located. There is a bell housing bolt missing.
No problem for us as that bolt can be left out.

The latest RX8 low power auto tx engines appear to
be the same as the high power version. I cannot confirm this yet.
The change occurred around 2006 I think.

Thanks for the bolt location file.
